Having now described my invention, what l claim asy new, and desire tosecure by Letters Patent, is-

1. The combinationv of a cable of electric wires having a spliced joint,a sheath or box inclosing said splice and having packing-receivingsockets at each end, soft packingrings in said socket-portions, andcouplings screwedfinto said socket portions and compressing-the washerupon the cable.

2. The combination, with the spliced cable, of a protecting metalsheath' or cylinder adapted to cover the spliced portion of said cable,washers of soft material surrounding said cable on each side of thesplice, and means, substantially as described, to force said washers incontact with the cable to form a water-tight section.

3. The combination, with the spliced cable and an inclosing metal tubeinclosing said cable, ofa protecting metal sheath or box adapted tocover the spliced portion of said cable, couplings encircling said cableat each end of said sheath or box and uniting the tube and sheath orbox, and washers of soft material between said coupling ends and theends of the sheath or box, whereby,when said parts are drawn together,the washers are forced against the cable and make a tight joint.

4. The combination, with the spliced cable, oi a protecting sheath orbox adapted to cover the spliced portion of said cable, havingscrewthreaded ends, couplings encircling said cable at each end of saidsheath or box and provided with screw-threads upon their outer surfacesto screw into the sheath or box, and washers of soft material betweensaid couplings and the ends of the sheath or box,whereby, when saidparts are screwed together, they force the washers against the cable.

5. The combination of the cable A, having the spliced portion, the boxor sheath D, having projecting parts or collars E, couplings C, screwinginto the projecting parts or collars,

metallic rings F, having inner beveled edges, f, arranged within theprojecting parts, and washers G, adapted to be compressed within theprojecting parts or collars to make tight joints at each end of thesplice-box.

6. The combination of a spliced cable, an inclosing metal `splice-boxhaving its edges beveled and provided with an internallyscrew-threadedpart projecting beyond the beveled edges, soft washers or packing-ringswithin said projecting parts, and couplings which screw into theprojecting part of the splice-box and compress the washers.

7. The combination of a cable of electric wires having a spliced joint,a sheath or box nclosing said 4splice and having packing-rec eivin gsockets at each end, soft packing-rings in said socket portions,packing-receiving metallic rings upon each side of the packing, andcouplings screwed into said socket portions and compressing the washerupon the cable.

8. The combination of the sheath or box D, having its ends provided withcollars E, forming socket portions at each end, annular rings H and Fwithin said socket portion, a soft washer, G, between the annular rings,and couplings C, screwed into said socket portions to compress the ringsH upon the washer.

9. The combination of the sheath o r box D, having its ends providedwith collars E, forming socket portions at each end, annular rings H andF within said socket portions, a soft washer, G, between the annularrings, couplings C, screwed into said socket portions to compress therings H upon the washer, and

the conduit-pipe B, screwed into the coupn lin gs, substantially as setout.
